The z/OS® Communications Server TCP/IP contains a high-speed cache that is referred to as the Fast Response Cache Accelerator. You can configure the WebSphere® Application Server on z/OS® to cache static and dynamic content into the FRCA cache.
The FRCA cache only supports non-SSL connections at this time. The z/OS Communications Server TCP/IP service updates to the FRCA support are required for this function to work on z/OS Version 1.9. If the updated FRCA services are not available on the system the application server will issue error message BBOO0347E or BBOO0348E. TCP/IP utilizes CSM storage to maintain the cache.
To enable cache accelerator for caching static and dynamic content, such as servlets and JavaServer Pages (JSP) files, configure WebSphere® Application Server:
f bbos001,display,frca
f bbos001,display,frca,stats
f bbos001,display,frca,content
DISPLAY TCPIP,,NET,CACHFRCA services can be restricted. If access is restricted, WebSphere Application Server must be granted access. The following RACF command enables access to the FRCA services:
PERMIT EZB.FRCAACCESS.SY1.TCPIP CLASS (SERVAUTH) ID (CBSYMCR1) ACCESS (READ) SETRPOTS RACLIST (SERVAUTH) REFRESH
